Digitry’s GB1 is a temperature controller that couples flexibility of programming with ease of operation. In addition to its use for annealing glass, the GB1 is a favorite of artists doing pâte de verre, lost wax casting, slumping, fusing, kilncasting, ceramics, crystalline glazing etc.

Ramps and soaks can occur in any combination. Each profile can have 15 steps of up to 99 hours each, allowing a total time of over 8 weeks. Plus, the GB1 can store 10 distinct profiles that can be instantly retrieved. For longer or more complex annealing, profiles can be linked.

The GB1 is the third generation of programmable temperature controllers designed and manufactured by Digitry since 1981. It incorporates the proven features of Digitry’s internationally bestselling GB4 — simplicity, reliability and advanced digital electronics — into a unit designed for glass and ceramic artists who need sophisticated control of a single annealing oven, kiln, lehr or furnace. Simply key in the points of your profiles and let Digitry do the rest!

Features and Benefits

Up to 15 set points for each of 10 separate temperature profiles gives you a nearly limitless number of temperature profiles with automatic calculation and control of ramps between set points.

How easy is it to program your GBl? As this sample program shows, its just as easy as using a pocket calculator.

GB1 Specifications

The GB1 Programmable Temperature Controller, standard unit, is designed for use with a Type K thermocouple. Temperature readings are in degrees Fahrenheit. Key lock security, Celsius temperature readings and European options are available.

If you have a need to control up to five annealing ovens, let us give you the facts on our GB5 Programmable Temperature Controller. You’ll see why Digitry has set an international standard for microprocessor-based temperature controllers.

Please view our web pages at www.digitry.com, where you can find additional information, including product descriptions and manuals, usage tips, price sheets, and order forms.

Since the beginning of 2002, Digitry's GB1 has been available with a choice of two interfaces: the Classic Interface and the Step-Time Interface. With the Classic Interface, the user enters the total time from the beginning of the profile to the end of each step. With the Step-Time Interface, the user enters the time just for each step itself. Manuals for both interfaces are available below.
